Transport equipment

ABSTRACT

A transport equipment comprises at least a carrier that is disposed on the window platform or balcony and thus becomes one part of a building in normal condition, or that is pushed out of the window or balcony for personnel and commodity transportation through a cantilever beam of a slow descending mechanism when in need, to descend or ascend along the outer wall of a building. In this manner, personnel or commodity can be transported by the carrier to reach ground directly or in relay-floor connection mode. For example, personnel or precious commodity can be evacuated at the first instant of fire. Even in the case of electricity disconnection due to the happening of a fire, the slow descending mechanism of the transport equipment can be operated by uninterruptible power supply or by hand.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a transport equipment, more particularly to a transport carrier (simply carrier hereinafter) that is disposed on the window platform or balcony and thus becomes one part of a building in normal condition, and that is pushed out of the window platform or balcony for personnel and commodity transportation through a slow descending mechanism in emergency condition.

2. Brief Description of the Prior Art

Ordinary building is designed to have windows or balcony for good lighting, ventilation and landscape. However, iron grille for burglar proof added in most cases for safety consideration is apt to become an obstacle for escaping in emergency condition, thus great loss in life or property will be suffered.

In order to improve the defect of retardation on escaping caused by the adding of iron grille in traditional building, the inventor of this application has proposed a “BURGLAR PROOF METAL GRILLE FOR ESCAPING” disclosed in Taiwan Patent No. M 286860, in which a cage type carrier can be descended slowly to reach ground after the accommodation of personnel. In this way, personnel can get rid of danger or terrible feeling occurred in the case that he/she have to clamber out of a window and to climb down along a ladder for escaping, characterized in that it comprises a metal grille frame body fixed on the wall surface of a building to serve as an accommodating chamber with a part of the frame face having no grille thereon; an escaping window cage body unfolded to be as a part of the accommodating chamber in normal condition, which includes a L shape frame body and a pair of movable frame bodies pivoted on both sides of the L shape frame body, the configuration after unfolding being complementary to the frame face of the L shape frame body without grille thereon and being fixed to be integral therewith, the movable frame body after detaching from the frame face without grille capable of being folded and assembled with the L shape frame body quickly to form a cage type carrier when in need; a slow descending mechanism formed by a suspending arm fixed on the wall surface of a building, a reduction mechanism, and a cable one end of which is connected to the escaping window cage body and the other end of which is coupled to the reduction mechanism through the pulley on the suspending arm. In this way, the carrier is unfolded and contained as a part of a burglar proof metal grille in normal condition, and is assembled to be a cage type carrier which can descend slowly along the outer wall of the building in emergency condition.

Without doubt, the above proposal disclosed in Taiwanese Patent No. M 286860 provides a solution to improve the defect of retardation on escaping caused by the adding of iron grille in traditional building, however the person skilled in the art can understand that the carrier is easy to swing due to the impact of wind during descending process. Thus, the person in danger further suffers additional terrible feeling from swinging in the air. Therefore, improvement for better safety is expected.

SUMMARY OF THE INVENTION

The main object of this invention is to provide a transport equipment, which can remove the defect of retardation on escaping caused by the adding of iron grille in traditional building, and which can eliminate the swinging of carrier occurred by the impact of wind in the air during descending.

In order to achieve the above and the other objects, the transport equipment of one aspect of the present invention mainly comprises: a carrier accommodated on the window platform or the balcony of a building, which has a plurality of suspending cables and at least a pair of pulleys provided on the bottom; a slow descending mechanism disposed on the inner wall of the building and above the carrier, having a pair of swinging arms swingable to the outside and a pulley provided at the end of each swinging arm; a pair of winches for winding cables, one end of each cable being fixed on the winch and the other end extending over the pulley and going downwardly to anchor together with the suspending cable; a pair of reduction mechanisms operative to restrict the winches rotating at a predetermined speed; a pair of guide rails provided vertically on the outer wall of the building; and a pair of push rods operative to push the swinging arms to the outside and to allow the pulleys of the carrier engaging on the guide rails.

According to the above structure, the carrier in normal condition is disposed on the window platform or balcony and thus becomes one part of a building, and is pushed out of the window platform or balcony by the swinging arms of the slow descending mechanism so as to slide on the guide rails provided on the outer wall of the building. Thus, personnel or precious commodity can be evacuated at the first instant of fire.

According to this invention, the carrier conducts ascending and descending along the fixed guide rails provided on the outer wall of a building, so the transport stability can be improved. Therefore, the carrier can be constructed to have the floor or the sidewalls having increased grille density so as to increase safety feeling of personnel. The carrier can be used in apartment or building with less floors so as to transport old people or handicapped person. This is another object of the present invention.

According to still another aspect of the invention, a solution for eliminating the defect of retardation on escaping from enclosed space such as high building having curtain wall is proposed. In addition to the above carrier and the slow descending mechanism, a connection platform on a floor for relay purpose is utilized for temporarily transferring personnel or commodity to the safe floor or to the floor accessible by the aerial platform of a aerial ladder fire fighting truck. This is still another object of this invention.

According to this aspect of the invention, the transport equipment includes a control unit electrically connected with the reduction mechanisms, push rods and connection platforms through, for example, smoke detectors, temperature sensors or the other fire alarm detecting devices, so that a predetermined safety procedure is automatically executed. In addition, the transport equipment is electrically connected with an uninterruptible power supply system located at a safe place. Even in the case of electricity disconnection due to the happening of a fire, the transport equipment can still be operated by uninterruptible power supply system or by hand. This is still another object of the present invention.

According to still another aspect of the invention, a powerless transport equipment is proposed to eliminate the defect of retardation on escaping from enclosed space such as high building with curtain wall, in which two carriers alternately move upward and downward simultaneously along the guide rails provided on the outer wall by providing different weights on the carriers connected at both ends of a cable. This is still another object of the present invention.

According to yet another aspect of the invention, a solution for space saving of window platform or balcony in non-use condition of the carrier is proposed. For example, the carrier is composed of several face structures, and a plurality of telescopic tubes are provided between two main face structures. In this way, the depth of the carrier can be enlarged or shrinked. In shrinked state, each telescopic tube of the carrier can be received within respective elongate receiving groove in the window platform such that the depth of the carrier can be shrinked to a minimum value. Thus, the carrier becomes a part of the iron grille. When in need, the carrier is pushed out of the window platform and is enlarged in depth dimension so as to increase the transport capacity. This is another object of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The technical features of the present invention will become more apparent by the detailed description of following embodiments, which are merely illustrative rather than restrictive on the scope of the present invention, in conjunction with the attached drawings.

In FIG. 1-6, the first embodiment of the transport equipment of the present invention operated in combination with a building is shown. Generally, building 1 with RC structure basically has a window platform 11 or balcony provided on the outer wall 10 for good lighting, ventilation and landscape. For the sake of safety, iron grille for burglar proof is added in most cases. This invention utilizes the outer wall 10 of the building 1 to transport personnel or commodity in emergency or in need condition. The transport equipment of the present invention mainly comprises a carrier 20 accommodated on the window platform 11 and thus becomes a part of the building, for example, by decorated it identically with the iron grille 20′ to become a part of the iron grille 20′ as shown in FIG. 5. A plurality of suspending cables 21 for sustaining the weight of the carrier 20 are provided on the top of the carrier 20, and at least a pair of pulleys 22 are provided on the bottom.

A slow descending mechanism 30 is disposed at a location above the carrier 20, and is fixed on the inner wall 13 of the building 1 through a base 31. The slow descending mechanism 30 comprises a pair of cantilever beams 32, one end of each beam 32 being fixed on the base 31 and the other end extending outside. A pair of swinging arms 40, forming as a bent shape hanging toward the carrier 20, one end of each swing arm 40 pivots on the suspending arm 32, and the other end is provided with a pulley 41. A pair of winches 50, fixed on the base 31 and above the suspending arms 32, are used respectively to wind a cable 51 which has one end fixed on the winch 50 and the other end extending over the pulley 41 and going downwardly to anchor together with the suspending cable 21. A pair of reduction mechanism 60 are disposed on the base 31 and below the pair of winches 50, which can be a hydraulic reducer or a gear reducer (not shown). In this embodiment, the reduction mechanism 60 is illustrated as a hydraulic reducer. Each hydraulic reducer has an actuating rod 61 for acting eccentrically on the pair of winches 50 so that each winch 50 can rotate at a predetermined speed. A pair of guide rails 12 are arranged vertically on the outer wall 10 of the building 1. A pair of push rods 70, for example a pair of hydraulic actuated telescopic rods or hand-wheel operated screw rod (not shown), are provided below the slow descending mechanism 30. One end of each push rod 70 is fixed on the inner wall 13 of the building 1, and the other end is interlinked with a swinging arm 40 through a link 71 so that each swinging arm 40 is pushed outwardly. At the same time, each pulley 22 of the carrier 20 engages with the guide rail 12 (as shown in FIGS. 2 and 3).

According to this invention, the guide rails 12 can be formed by a pair of channel steels with C-section, and are disposed on the outer wall 10 of the building 1 with the openings 12 a facing oppositely with each other. The carrier 20 is provided with a pair of pulleys 22 fixed on the upper and lower end of the rear edge of each side face, thus the total quantity of pulleys on the carrier 20 would be 4 in this case. A baffle plate 121 is provided at the outer edge of the opening 120 of the channel steel of each guide rail 12 for precisely loading the pulley 22 into the sliding groove in the guide rails 12. In addition, this invention further includes a control unit (not shown) and an uninterruptible power supply device that are electrically connected with the reduction mechanisms 60 and the push rods 70. As shown in FIGS. 5 and 6, the carrier 20 is pushed out of the window platform 11 through the swinging arms 40 of the slow descending mechanism 30, and conducts ascending or descending along the guide rails 12 provided on the outer wall 10 of the building 1 so as to transport personnel and commodity when in need. In this manner, personnel or precious commodity can be evacuated at the first instant of disaster. Even in the case of electricity disconnection due to the happening of a fire, the slow descending mechanism of the transport equipment can be operated by uninterruptible power supply or by hand.

Furthermore, the carrier 20 can be constructed in such a manner that it takes a less part of the window platform in non-use condition, and is enlarged to have more transport capacity in use condition. A variation of the carrier 20 is shown in FIGS. 7 a to 7 d. As shown in FIG. 7 a, the carrier 20 is formed by a plurality of horizontal and vertical tubes 201. A telescopic core member 202 is contained within each tube 201 (as shown in FIG. 7 b). As shown in FIG. 7 c, a flange portion 201 a is formed to project inwardly at one end of each tube 201, while a flange portion 202 a is formed to project outwardly at one end of each telescopic core member 202. The flange portion 201 a of the tube 201 engages with the flange portion 202 a of telescopic core member 202 when it is drawn out, so as to achieve easy positioning between each tube 201 and its telescopic core member 202. When the carrier 20 is not in use, each telescopic core member 202 is retracted into the inside of respective tube 201, and several locking pins 203 are used for locking at some selective points. Thus, the size of the carrier 20 is shrinked to a minimum value. When in need, the carrier 20 is raised by the swinging arms 40 of the slow descending mechanism 30 and is enlarged both in the width direction and in the height direction after the locking pins 203 are released, and again the locking pins 203 are used for locking at some selective positions after the completion of the enlargement of the carrier 20. Thus, the transport capacity of the enlarged carrier 20 is increased (as shown in FIG. 7 d).

In FIGS. 8 to 10, the second embodiment of the transport equipment of the present invention operated in combination with a building having curtain wall is shown. As to a skyscraping building 1 having curtain wall, the raising stroke of the aerial ladder of a fire fighting truck is limited and might be unable to give access to higher floor. On the other hand, the fire fighting regulation requires that escape window 11′ must be provided at some fixed location of each floor. Thus, this invention takes advantage of the escape window 11′ and the curtain wall 10′ to transport personnel and commodity in emergency or in need.

According to the transport equipment of this embodiment, the basic structure is substantially the same as the above embodiment, therefore repeated description thereof is omitted. The carrier 20 is accommodated in a window platform of an escape window 11′ as a part of building. For example, the carrier 20 has a decoration panel 10 a which is almost the same as the curtain glass 101, therefore the carrier 20 is a part of the curtain wall 10′ when seen from the outside. As shown in FIG. 10, the guide rail 12 is formed on an extension having C shape channel integrally formed with the Aluminum-extruded frame 102 for supporting the curtain glasses 101, with the opening 12 a facing outside of the building 1. Correspondingly, the carrier 20 is provided with a pair of pulleys 22 fixed on the upper and lower end of the side edge of the rear surface, thus the total quantity of pulleys 22 on the carrier 20 would be 4 in this case. The positioning of the pulleys 22 in the guide rails 12 can be conducted in the same way as the first embodiment.

In the case of a skyscraping building with curtain wall, direct ground-reaching of the carrier 20 not only takes much time but also influences the evacuation of the other people. Therefore, a method of connection is utilized in this embodiment. In other words, personnel are transferred to a safe floor or the floor that is accessible by the aerial platform of an aerial ladder fire fighting truck. Several escape window 11′ are provided on some lower floors of the building 1 having curtain wall, and connection platforms 100 can be provided on some selected suitable escape windows (11′) of certain floors. The connection platform 100, for example is a plate body controlled by a pair of hydraulic actuated telescopic arms 103 so as to be extended from the escape window 11′ to the outside. In this manner, the connection platform 100 can provide temporary docking for the carrier 20 (as shown in FIGS. 8 and 9). The operation of the transport equipment and the connection platform 100 is automatically conducted according to a predetermined safety procedure through the detection of a fire by smoke detectors, temperature sensors or the other fire alarm detection devices.

In FIGS. 11 and 12, the third embodiment of the transport equipment of the present invention operated in combination with a building having curtain wall is shown. The transport equipment in this embodiment has two carriers 20, 20′ alternately moving upward and downward simultaneously along the guide rails provided on the outer wall 10′ of the building 1′ by providing different weights on the carriers connected at both ends of a cable, so that personnel and commodity can be transported in powerless mode.

According to this invention, a pair of escape windows 11′ are provided respectively at an upper location and a lower location on the outer wall 10′ of the building 1′, and are separated with each other at a suitable transverse distance. A pair of carrier 20, 20′ are accommodated within the respective escape window 11′. A pair of suspending cables 21 are provided on the top of each carrier 20, 20′, and at least a pair of pulleys 22 (not shown in the figures, this part is almost the same as that in the first embodiment hence repeated description is omitted) are provided on the rear surface of each carrier 20. A loading plate 15 is provided at the top of the building 1, such as below the canopy, which can slide out by suitable guiding on the rail (not shown). Corresponding to the each suspending cable 21 on the carrier 20, a deflection pulley 43 or 44 is provided on the loading plate 15 atop the suspending cable 21 on each carrier 20, 20′. Two cables 51, 51′ of equal length, connect these two carriers 20, 20′ respectively. The cable 51 is connected at the suspending cables 21 of the right-hand side of each carrier 20, 20′ and passes over the deflection pulley 44 and 43, while the other cable 51′ is connected at the suspending cables 21 of the left-hand side of each carrier 20, 20′ and passes over the deflection pulley 44′ and 43′. Both ends of each cable (51, 51′) are anchored together with the corresponding suspending cable (21). In operation, these two cables 51, 51′ have to move at same pace. A reduction mechanism 62 is used to restrict each deflection pulley 43, and 44′ rotating at a finite rotation speed. Two pair of guide rails 12 are provided vertically on the outer wall 10′ of the building 1′ (this part is the same as that in the second embodiment hence repeated description is omitted). A hand-wheel 72 is used to rotate a screw rod 73 so that the loading plate 15 moves outward and the pulleys 22 on the carrier 20, 20′ can slide into the respective sliding groove in the guide rail 12 (this part is the same as that in the second embodiment hence repeated description is omitted).

When in need, the hand-wheel 72 and in turn the screw rod 73 are rotated to move the loading plate 15 outward so that the carrier 20, 20′ are pushed out of the escape windows 11′. The two carriers 20, 20′ move alternately upward and downward simultaneously along the guide rails 12 provided on the outer wall 10′ of the building 1′ by providing different weights on the carriers 20, 20′, so that personnel and commodity can be transported in powerless mode.

In FIGS. 13 to 15, the fourth embodiment of the transport equipment of the present invention operated in combination with a building of RC structure is shown. The suspension structure for the transport equipment in this embodiment is substantially the same as that in the third embodiment, hence repeated description thereof is omitted. Generally, building with RC structure has a pair of window platforms 11 (or balcony) provided on an upper location and a lower location on the outer wall 10 of the building 1, and are separated with each other at a suitable transverse distance. A pair of carrier 20, 20′ are accommodated within the respective window platform 11 and thus become a part of the building in normal condition. For example, the carriers 20, 20′ are decorated to be identical with the iron grille and thus becomes a part of the iron grille.

As shown in FIGS. 14 and 15, the carrier 20 or 20′ is composed of two face structures 20 a, 20 b, each face structures 20 a, 20 b is formed by a plurality of horizontal and vertical tubes 201. A plurality of telescopic tubes 202 are connected between the two face structures 20 a, 20 b at both sides and the bottom. One end of each telescopic tube 202 is fixed on the face structure 20 a; the other end passing through the hole on the face structure 20 b is formed with a flange portion 202 a. Thus, the face structure 20 b is allowed to move along the telescopic tubes 202 in such a manner that the depth of the carriers 20, 20′ can be enlarged or shrinked. Conventional collapsible grilles 204 can guard the side faces of the carriers 20, 20′. Corresponding to the telescopic tubes 202, a plurality of elongated receiving grooves 111 are provided in the floor 110 of the window platform 11. Thus, the telescopic tubes 202 in non-use state of the carrier 20. 20′ can be received within the elongated receiving grooves 111, so that the depth of the pair of carrier 20, 20′ can be shrinked to a minimum value. In addition, a pair of guide rails 12 for each carrier formed by C shape channel steel are provided vertically on RC structure of the outer wall 10 of the building 1. A pair of pulleys 22 is provided at each side of the face structure 20 b of each carrier 20, 20′ for sliding contact within the opening 12 a of the guide rails 12.

When in need, the hand-wheel 72 and in turn the screw rod 73 are rotated to move the loading plate 15 outward so that the carrier 20, 20′ are pushed out of the windows platform 11. The carriers 20, 20′ are enlarged in the depth direction and are locked by conventional lock pin, and subsequently move alternately upward and downward simultaneously along the guide rails 12 provided on the outer wall 10 of the building 1 by providing different weights on the pair of carriers 20, 20′, so that personnel and commodity can be transported in powerless mode. The person skilled in the art should understand that the pair of carrier 20, 20 of this embodiment are possible to be applied to the case of two neighborhood buildings. In other words, one carrier mounted in one build is connected to the other carrier mounted in the neighborhood building.

In FIGS. 16 to 21, the fifth embodiment of the transport equipment of the present invention operated in combination with a building of RC structure is shown. Generally, several window platforms 11 (or balcony) are provided on the outer wall 10 of building 1 having RC structure. The transport equipment of this embodiment comprises at least one carrier 20 that is accommodated in the window platform 11 and thus becomes one part of the building. For example, the carrier 20 is decorated to be identical with the iron grille and thus becomes one part of the iron grille when viewed from outside (as shown in FIG. 16).

As shown in FIGS. 17 and 18, the carrier 20 has a first face structure 20 a, a second face structure 20 b and a third face structure 20 c formed respectively at the front face, the rear face and the bottom face. A pair of telescopic tubes 202 is provided on each side faces of the carrier 20 disposed between the first face structure 20 a and the second face structure 20 b. One end of the each telescopic tube 202 is connected at the respective corner of the first face structure 20 a, while the other end passing through the hole of the second face structure 20 b is formed with a flange 202 a. The second face structure 20 b is allowed to slide along the telescopic tube 202 till the flange 202 a. A cable 51 is respectively stretched atop the first face structure 20 a and the second face structure 20 b. The third face structure 20 c is disposed at the bottom between the first face structure 20 a and second face structure 20 b. One end of the third face structure 20 c pivots on the lower side of the first face structure 20 a so that the other end is thus rotated and folded into the first face structure 20 a. Therefore, the depth of the carrier 20 can be shrinked or enlarged. A pair of drive gears 23 is provided symmetrically on both sides of the second face structure 20 b, and a pair of idler gears 23 a is provided on the same sides opposite to the pair of drive gears 23. Further, a pair of reduction mechanisms 60 fixed on the carrier 20 act on the pair of drive gears 23 so that the pair of drive gears 23 can be rotated at a predetermined speed in coordination with power drive mode or powerless mode. On the other hand, a plurality of elongated receiving grooves 111 corresponding to the telescopic tubes 202 are provided in the floor 110 of the window platform 11. Thus, the telescopic tubes 202 in non-use condition of the carrier 20 can be received within the elongated receiving grooves 111, so that the depth of the pair of carrier 20 can be shrinked to a minimum value.

Besides, a pair of guide rails 12 is arranged vertically along the outer wall 10 of the building 1. As shown in FIG. 19, the pair of guide rails 12 is made of C type channel steel and is fixed on the outer wall 11 of the building 10 with the openings 12 a facing oppositely to each other. A rack 123 is provided at the inner side of the opening 12 a of each guide rails 12. A pair of horizontal accommodating sections 122 is provided on each guide rail 12 for receiving the drive and idler gear 23 and 23 a respectively.

When in need, the carrier 20 is pushed out of the window platform 11 by outside force and is enlarged in depth direction. Each drive gear 23 is meshed with the rack 123 of each guide rail 12 so that the carrier 20 can transport personnel and commodity in power drive or powerless mode as shown in FIGS. 20 and 21.

The above embodiments are for illustrative purpose only, not for the restriction of the scope of the present invention. The equivalent modifications and variations made without departing from the spirit and principle of the present invention are considered still within the scope of the present invention.
